Impact of diet and age on element excretion from dogs
Dog (Canis familiaris L.) excreta may pollute the environment. However, little is known about the nature of canine feces and urine. A study was conducted to determine effects of age (young adult and geriatric) and diet (160, 240, or 320g crude protein (CP) kg-1 feed) on element concentrations in female beagle excreta. Age had no significant effect on element concentrations in feces or urine. Increasing dietary CP significantly increased fecal carbon (C; P > F= 0.0001) and nitrogen (N; P > F= 0.0001) concentrations, but decreased C:N (P > F= 0.0001). Canine fecal phosphorus (P) concentration was higher than typical values reported for feedlot cattle, broiler chickens, and swine produced in concentrated animal feeding operations. Fecal P concentration decreased when CP was increased from 160 (45.6 g P kg -1) to 240 g kg-1 (39.2 g P kg-1), suggesting that dietary manipulation has potential to decrease P discharge to the environment.
